An element has a half-life of 30 years. If you start with 10g of this element, how many grams of this element would remain after
drek231 [11]

After two half-lives or 60 years, 7.5 g of the element will be left.

<u>Explanation:</u>

<u>Half-life:</u>

  • In simple words, Half-life can be defined as the amount of time needed for a quantity to fall to half its value as contained at the beginning of the time period.
  • In this problem the half-life of the element is thirty years, then after thirty years half of the sample would have decayed and half would be left as it is.
  • After thirty years (The first half-life ) 30 /2 = 15 g declines and 15 g remains disappeared.
  • And after another sixty years (The two half-lives) 15 /2 = 7.5 g declines and 7.5 g remains disappeared.
  • After two half-lives or 60 years, 7.5 g of the element will be left.

What are the phases in meiosis and explain
densk [106]

Cell division happens twice during meiosis. One starting cell can produce for gametes (eggs or sperm.) In each round of division, cells go through four phases called prophase, metaphase, anaphase, and telophase.

prophase During prophase the chromosomes become visible as paired chromatids and the nuclear envelope disappears. This phase includes reduction division, which is where the number of chromosomes is decreased from 46 (diploid) to 23 (haploid.)

metaphase This is where the 23 remaining chromosomes become attached to the spindle fibers.

anaphase During this phase, the chromosomes move away from each other to one or the other pole of the spindle fiber.

telophase In which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.

interphase This is a resting period.
